"Height is a typical polygenic trait. In other words, the amount of human affects a large number of genes. Therefore, the results of our research do not give a clear answer as to why someone measured two meters and another only forty meter. We found only the first gene that has an impact on the amount and assume that we can find them a lot more. Apparently only a few hundred, "said Tim Frayling from Peninsula Medical School in a study published by the journal Nature Genetics.
http://health.reviewship.com/grow-taller-4-idiots-review/ This modest, actually "only" step in deciphering the genetic code, however, require a lot of effort scientists. The research is in fact attended to five thousand volunteers who were willing to provide a DNA sample and information on height and weight. After analyzing this data, scientists have identified a gene HMGA2 as one of the most promising and subsequently compared with data obtained from another 30-thousand people. This shows that the full realization of knowledge about the human genome is much more labor-intensive than originally anticipated.
On the independent press conference to confirm the Craig Venter, one of the pioneers of deciphering the human genetic code and the first person who can construct a complete map had its own genes. Now this map further clarified and pointed to the fact that his genetic makeup from the basic human genome differs on more than four million sites.
